Patent GB-2117575-A (GB)
Title: Electrical connector
Inventor: MCCORMICK DAVID M
IPC: H01R13/52
Filed: 1983-02-28
Abstract: The plug 21 of a plug and receptacle connector has an outer hollow cylindrical coupling ring 24 rotatable with respect to the plug body and includes internal threads 40 that cooperate directly with threads 39 on the plug body outer surface. Rotation of the coupling ring serves to drive the plug and receptacle 20 toward or away from each other depending on the direction of rotation thereby connecting and releasing the connector parts, respectively. Resilient interface seals 30, 51 which engage each other compensate for accumulated tolerances of the assembled connector parts thereby obviating the need for a separate threaded coupling nut prevalent in prior art structures. The contacts are mounted in insert assemblies 29, 30, 31, and 48, 49, 51 each assembly being of unitary bonded form with resilient grommets 29 and 48 for wires 22, 23 and rigid insulators 31, 49.

Patent GB-2119608-A (GB)
Title: Digital display system
Inventor: PRATT JOHN MORLEY
IPC: G09G5/20
Filed: 1983-04-26
Abstract: The system displays linear features on a grey-scale or other multiple-intensity display device with greater apparent smoothness by selecting the intensities of picture elements in the neighbourhood of the feature in dependence on their closest distances to the feature. Straight lines (e.g. 10) are generated by a vector generator which conducts scans (5, 6 etc.) across the line. The closest distance (d) from the picture element currently reached by the scan to the centre of the line is held in an accumulator (18), which at each step of the scan is incremented or decremented from a register (20 or 21) holding the change in the distance. Each scan is terminated, and another scan in the opposite direction commenced, when a comparator (26) indicates that the intensity has reached that of the background. This scanning technique allows lines of varying width (w) to be displayed easily. The position (L) of the picture element along the line is held in an accumulator 19, used to address a table (22) holding the width at that point. A similar scanning technique is used in a circle generator. <IMAGE>

Title: Self-loading hand weapon
Inventor: JAKUBASCHK HORST
IPC: F41A3/72
Filed: 1983-05-06
Abstract: A self-loading hand weapon, preferably a rifle, is provided with an opening 3 in a part rigid with the barrel 1, said opening being perpendicular to the barrel axis and housing a coaxial cylindrical breechblock 4 which can be pivoted about its longitudinal axis for loading and which contains a cartridge chamber 9 which aligns with the barrel 1 when the breechblock 4 is in a firing position and which is sealed off at the rear, and with an arrangement for pivoting the breechblock 4 out of the firing position into a loading position in which the cartridge chamber 9 is accessible for introducing a cartridge 14, and for pivoting the breechblock 4 into a firing position after the introduction of the cartridge whereby, owing to the arrangement for pivoting, particularly owing to a switch-wheel drive, the breechblock 4 is only rotatable in one direction. There is a rotatable flywheel (40, 42, 46, 48, 54, 56, 58, Fig. 2 not shown) which has a drive connection to the breechblock 4 such that in the period of time after the firing of a round up to the time when the weapon is ready to fire the next round the flywheel is constantly in rotation and during at least a part of the aforementioned period of time delivers stored kinetic energy for driving the breechblock. Shock loading is thus reduced. <IMAGE>

Patent GB-2139844-A (GB)
Title: Regulating scanning lines of an image reproducing system
Inventor: YAMADA MITSUHIKO
IPC: H04N1/21
Filed: 1984-01-31
Abstract: Image data, eg for facsimile reproduction, after digitizing is treated by matrix processing such as fast fourier transform, which requires several (N) successive scan lines of elements to be available at the same time. To avoid sequential loading and unloading lines of digital buffer memory, each line in turn is fed into latch 31a and directly out via latch 32a to a shift register. Simultaneously the line is also fed from latch 32a to the data input of line memory 31b. Memory 31b already holds the previous line, and as this is read out through latch 32b to the shift register and to memory line 31c, the next line is written in to 31b in its place. As each of the (N-1) memories are read out, they are refilled by the following line, the data stored in the last memory (31e) being discarded. After data has been loaded into the shift register, a processing circuit calculates according to the required algorithm. <IMAGE>
